Yes, the relative acceleration of nearby objects is the hallmark of spacetime curvature. In answer to your second question, much* of GR can be explained in those terms. In fact, we sometimes use an equation called the Raychaudhuri equation which tells us the rate at which geodesics converge as one moves through spacetime.

* Not all, unfortunately, for this reason -- "If the rotational . . ." etc.
